City of Hunger is a game where the cast is seen in another canon (Stand Still Stay Silent), so there may be some confusion if you search for Lalli or Onni. But in this universe, they are cyborgs: http://www.hummingfluff.com/?id=devlog&postin=24 (Looks like they have multiple robotic limbs, although we don't know the extent of it, if they have mechanical hearts or something.)

For Voltron: Legendary Defender, The Fun Sentry is this guy. That seems to be the only name the fandom knows him as.
